摘要： The invention relates to methods for detecting at least one of a downlink grant and an uplink grant within a sub-frame of an OFDM-based mobile communication system. The invention provides a reception apparatus (e.g. a relay node or a mobile terminal) that are adapted to perform these methods. The invention defines the uplink grant search space to form a subset of the downlink grant search space. In other words, in the frequency domain, the uplink grant search space is defined on a subset of the resource block pairs that form the downlink search space. This configuration allows downlink data to be mapped to the remaining resources outside the uplink grants search space and the resources used for a downlink grant. Furthermore, the downlink grants comprise an indication of whether the uplink grant search space in the sub-frame comprises (user) data or not.

摘要： A base station device causing no decrease in system throughput and guaranteeing the reception quality at a terminal when a DCI directed toward the terminal is mapped to a PDCCH region and an R-PDCCH region. A search space setting unit (103) sets a search space having a plurality of allocation candidates, in both regions. An allocation unit (106) allocates control information to a resource in one allocation candidate in the search space. The ratio of the number of allocation candidates in the R-PDCCH region to the number of allocation candidates in the PDCCH region in the search space for a terminal using DM-RS in the R-PDCCH region is equal to or greater than the ratio of the number of allocation candidates in the R-PDCCH region to the number of allocation candidates in the PDCCH region in the search space for a terminal using CRS in the R-PDCCH region.

摘要： In a wireless relay method for relaying a signal between a base station and a mobile station, if an SRS is transmitted in a subframe immediately previous to the backhaul subframe, the last symbol of an access link subframe is set as a fake symbol in which the SRS that the mobile station transmits to the wireless relay device is not configured. The signal transmitted from the mobile station to the wireless relay device in a previous symbol of one of the fake symbol is received, and switched to transmission from the wireless relay device to the base station. If the SRS is not transmitted in a subframe immediately previous to the backhaul subframe, the signal transmitted from the mobile station to the wireless relay device is received in the last symbol of the access link subframe, and switched to transmission from the wireless relay device to the base station.

摘要： A wireless relay device and a wireless relay method are provided which can improve the utilization efficiency of resources. In the wireless relay device for relaying a signal between a base station and a mobile station, if a transmission section transmits an SRS in a subframe immediately previous to the backhaul subframe, an SRS setting section sets a last symbol of an access link subframe as a fake symbol in which the SRS that the mobile station transmits to the wireless relay device is not configured. A reception section receives the signal transmitted from the mobile station to the wireless relay device in a previous symbol of one of the fake symbol, and then a switching section switches to transmission from the wireless relay device to the base station. If the transmission section does not transmit the SRS in the backhaul subframe immediately previous to the backhaul subframe, the reception section receives the signal transmitted from the mobile station to the wireless relay device in the last symbol of the access link subframe, and then the switching section switches to transmission from the wireless relay device to the base station.

摘要： The present invention relates to rapid search space reconfiguration for E-PDCCH (Enhanced Physical Downlink Control CHannel) in wireless communication system to avoid flashlight interferences from neighbouring cells and to allocate the E-PDCCH on the best physical resource blocks (PRBs) in frequency fluctuation dominated scenarios. To this end, a method for providing low-latency feedback on a reconfiguration attempt of a search space for an Enhanced-PDCCH, and a corresponding apparatus are provided. Specifically, a signalling scheme is provided that supports transmission of both HARQ-ACK for PDCCH based E-PDCCH reconfiguration and HARQ-ACK for PDSCH (Physical Downlink Shared CHannel) on the same uplink subframe, so that an acknowledgment of PDCCH based E-PDCCH reconfiguration information and PDSCH information can be transmitted on the same subframe.
